Across
Petroleum-based organic compound that contains only hydrogen and carbon
Equal to the energy expended in applying a force of one newton through a distance of 1 meter
Heat transferred by way of electromagnetic energy.
_______ Point is the minimum temperature at which a liquid gives all sufficient vapors to ignite, but still not sustain combustion.
A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or a flame
Heat transfer method usually occurs through movement of hot smoke and fire gases
______ flammable limit is the minimum concentration of fuel vapor and air that supports combustion
The type of fuel that can be the most dangerous of all types
_______ stained windows is a heat indicator for a possible Backdraft
________ solvents. Flammable liquids that have an attraction for water
Is the tendency of gases to form into layers according to temperature(2wds)
________ cyanide colorless, toxic, and flammable liquid until it reaches 79°F (26°C). Above that temperature it becomes a gas with a faint odor similar to bitter almonds produced by the combustion of nitrogen-bearing substances
________ reaction releases energy in the form of heat and sometimes light

____ Point. Minimum temperature at which a liquid gives off enough vapors to form an ignitable mixture with air near the liquids surface
Indication of combustion by heat but without a spark or flame
A rapid oxidation process which is a chemical reaction resulting in the evolution of light and heat in varying intensities
A material that will maintain combustion under specified environmental conditions
The process of initiating self -sustained combustion
The type of energy that an object can release in the future
What method of heat transfer occurs when the material is heated as result of direct contact with a heat source
The stage of fire development when all the combustible materials in a compartment are burning
The energy possessed by moving object
_______ Pressure. Measure of the tendency of a substance to evaporate
_____ path is composed of at least one inlet opening, one exhaust opening, and the connecting volume between the openings.
Model of the four elements/conditions required to have a fire is a Fire___________
What fire stage occurs as the fuel is consumed and oxygen concentration falls
Carbon ________ a product of combustion, the most common product produced in structure fires
________ flame inhibition uses extinguishing agents to stop flame production
A model used to explain the elements/conditions necessary for combustion. the sides represent heat, oxygen and fuel
At 212oF (100oC) water is converted to________
Liquids with a specific gravity of less than one (<1) will: _________ on the surface
Lower limit at which a flammable gas or vapor will a ignight and support combustion. (acr)
______ Upper limit at which a flammable gas or vapor will ignite (acr)
